⚠️ SCIENTIFIC RESEARCH TOOL - DATA INTEGRITY MAINTAINED

STRICT DATA PRESERVATION RULES:
1. NO filtering, smoothing, or interpolation applied
2. ALL anomalies preserved for scientific analysis
3. NavIC is PRIMARY focus; other GNSS for comparison
4. Position is receiver-computed (multi-GNSS unless specified)
5. Derived metrics clearly labeled and traceable to raw data

NAVIC IDENTIFICATION: PRN 1-10 | Talker ID: GI | Constellation: NavIC/IRNSS
DATA SOURCE: Raw NMEA sentences from receiver
PURPOSE: Academic research & ISRO NavIC evaluation
